Can't download newest FTB Evolution server "version does not exist"

[dreia2k]

Hello,

when trying to install the newest version of the modpack https://www.feed-the-beast.com/modpacks/125 I'm getting an error.

My version variables are (resolves to pack version "1.5.0":

[...]
- name: FTB_MODPACK_ID
  value: "125"
- name: FTB_MODPACK_VERSION_ID
  value: "100010"
[...]

My container starting log:

[...]
+ case "${TYPE^^}" in
+ MODPACK_PLATFORM=FTBA
+ [[ -n FTBA ]]
+ case "${MODPACK_PLATFORM^^}" in
+ exec /start-deployFTBA
+ set -e
++ getDistro
++ grep -E '^ID=' /etc/os-release
++ cut -d= -f2
++ sed -e 's/"//g'
+ [[ ubuntu = alpine ]]
+ [[ -v FTB_MODPACK_ID ]]
+ [[ 125 =~ [0-9]+ ]]
+ [[ ! -n 100010 ]]
+ [[ 100010 =~ [0-9]+ ]]

+ return 1
+ '[' -f .ftb-installed ']'
++ cat .ftb-installed

+ ftbInstaller=/data/ftb-installer
+ arm=
+ [[ -f /data/ftb-installer ]]

+ /data/ftb-installer 125 100010 --noscript --auto

And in the /data directory the file ftb-installer.log says the following:

Server installer version 24.622.1046-linux-amd64 commit ea7895792cf8db92694f4feb3c54b6d9866b3d72
Running installer as user minecraft (1000)
2024/12/19 00:23:19 Error fetching modpack: version does not exist

For testing I only specified FTB_MODPACK_ID: "125" in which case the server version "12629" is downloaded automatically which resolves to the pack version "1.3.0".

Then I tested the ftb-installer on it's own and that seemed to work:

user@host:~/test/ftb_install$ ./ftb_installer -pack 125 -version 100010

 INFO  Fetched modpack:

       Is Update: false
       Install Path: /home/user/test/ftb_install
Do you want to continue? [Y/n]:

I'm unsure why and where the error get's produced. Could it be related to the FTB_MODPACK_VERSION_ID length?
It changed from 5 to 6 digits on the newer versions.

Maybe someone has encountered the same issue and knows a solution :)
Best regards

You seem to be running a slightly older version of the image. The newest names the download and runs the installer as ftb-installer-v2

[dreia2k]

Yes, thank you. That fixed it.

I had the stable image which doesn't include the new installer yet.

I tagged a new release so stable would be updated also
